Sorry for jumping on your thread, relax, but here are my responses, MrsB:
What's your lifestyle like?
Do you mostly walk (large comfy pram)?
drive (one that fits easily in the boot)? Sort of mixture. Walk to and from school every day. Sometimes to local shops, sometimesdrive to out of town shopping centre. Drive to and from older children's activities, eg dancing.
take the bus (one that folds with one hadn while you hold the baby?)? Thankfully, never.
Do you live somehwere rural where you need air tyres to get down footpaths or somehwere urban where manouevrability is more important? Urban but like the occasional rural walk. Prob no more than once a month.
Do you have oodles of space at home to store it or will it need to squeeze in the cupboard under the stairs? Cupboard under stairs but quite big.
Will you be using it for long periods (ie leaving child to sleep in it?) No
Do you want it to last till he's 4 or are you happy to buy another one later? Happy with a foldy-uppy for later.
What's your budget? About £5-600
